International Chemical Safety Cards D-LIMONENE ICSC: 0918 Carvene (R)-4-Isopropenyl-1-methylcyclohexene (+)-Limonene C10H16 Molecular mass: 136.23 ICSC #    0918 CAS #     5989-27-5 RTECS # GW6360000 UN #        see Notes EC #         601-029-00-7 April 20, 2005 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Flammable. NO open flames, NO sparks, and NO smoking. Powder, alcohol-resistant foam, water spray, carbon dioxide. EXPLOSION Above 48°C explosive vapour/air mixtures may be formed. Above 48°C use a closed system, ventilation, and explosion-proof electrical equipment. In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE STRICT HYGIENE!  •INHALATION Ventilation. Fresh air, rest.  •SKIN Redness. Pain. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •EYES Redness. Safety spectacles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Do not eat, drink, or smoke during work. Rinse mouth. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Personal protection: P1 filter respirator for inert particles. Do NOT let this chemical enter the environment. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Fireproof. Separated from strong oxidants.

International Chemical Safety Cards D-LIMONENE ICSC: 0918 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: Reacts violently with a mixture of iodine pentafluoride and tetrafluoroethylene, causing fire and explosion hazard. Reacts with oxidants. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK: sensitization of skin (Sh); IIb (not established but data is available); (DFG 2004). ROUTES OF EXPOSURE: INHALATION RISK: No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance is irritating to the skin and is mildly irritating to the eyes . EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization (see Notes). PHYSICAL PROPERTIES Boiling point: 178°C Melting point: -74°C Relative density (water = 1): 0.84 Solubility in water: at 25 °C very poor Vapour pressure, kPa at 20°C: 0.19 Relative vapour density (air = 1): 4.7 Flash point: 48°C c.c. Auto-ignition temperature: 237°C Octanol/water partition coefficient as log Pow: 4.2 ENVIRONMENTAL DATA The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish. N O T E S Sensitization may occur with the oxidized substance. This can occur when the pure or diluted substance has been kept for several days. UN 2052 (Transport Emergency Card 30S2052) and UN 2319 (Transport Emergency Card 30GF1-III) with Hazard class 3, Packaging group III are used in transport of this substance.
